Cruxial auto-repairs LLM tool call arguments
Cruxial is an open-source Python reliability layer that intercepts, validates, and auto-repairs LLM tool call arguments with sub-millisecond overhead. It works across major LLM providers and supports Model Context Protocol (MCP) servers to ensure downstream services receive clean, valid data.
Cruxial addresses a major pain point in LLM applications: the brittleness of tool calling due to argument hallucination.
* By correcting errors dynamically instead of just throwing exceptions, it prevents entire pipelines from failing on minor typos or schema mismatches.
* The sub-millisecond latency overhead makes it extremely practical for production environments where LLM response times are already a bottleneck.
* Its success will depend on how reliably the auto-repair logic handles complex schemas without inadvertently shifting the semantic intent of the tool calls.
